Installation of air valve and air outlet in clean room
A variety of air valves such as butterfly valves and multi-leaf valves are installed on the air duct system of the clean room. Before installation, check whether the frame structure is firm. The positioning, adjustment, braking and other devices should be accurate and flexible. Align the flange with the flange on the air duct or equipment, add gaskets and tighten the screws to make the connection firm and tight; the adjustment device of the valve should be installed in a position that is easy to operate; pay attention to the airflow direction of the air valve, and it should be The valve shell should be installed in the direction marked and must not be installed in reverse; the opening degree and opening direction of the air valve should be clearly and accurately marked on the valve body; the air valve installed at a high place should be 1-1.5m away from the ground or platform. ; For the air duct conveying dust and powder, a closed inclined flap valve can be used, and a butterfly valve should not be used. The inclined flap valve should form a 45° angle with the air duct along the airflow direction, and the flap valve on the vertical pipe should be 45° ° Angle installed against the direction of airflow.
Branch pipe air volume control valve plays a role in balancing the air volume of each air outlet. Since the opening process of the valve plate depends on the elasticity of the flexible wire rope, special attention should be paid to the position of the control valve during installation; the residual pressure valve is to ensure dust-free The important components that can maintain constant static pressure in the pharmaceutical cleanroom are installed under the wall of the clean room, and the tightness of the valve body and the wall should be ensured. The airflow flows out when the static pressure rises, and attention should be paid to the flatness of the valve plate and the adjustment rod of the weight to be free from impact and deformation, so that the adjustment of the weight is flexible. The tuyere is usually laid on the ceiling and the wall. The installation of all kinds of tuyere should be horizontal and vertical, firm and tight, and the surface should be flat. The tuyere installed on the ceiling should be closely coordinated with the civil construction, so that it is flush with the ceiling, and fixed on the ceiling with a keel; The size of the holes and the tuyere should be appropriate and kept tight. The tuyere with adjustment and rotation device should maintain the original degree of flexibility after installation. In order to keep the tuyere neatly indoors, the same type of tuyere installed indoors should be symmetrically distributed, and the tuyere in the same direction. The adjustment device should be on the same side. Zhongjing Global can provide consulting, planning, design, construction, installation, renovation and other supporting services for clean rooms and clean rooms.
The installation method of the rectangular linkage adjustable louver tuyere can be determined according to whether it is equipped with an air volume control valve. When installing a tuyere with an air volume control valve, the adjustment valve frame should be installed, and then the blade frame of the tuyere should be installed; the tuyere and the air duct When connecting, cut out a 10mm connection tenon at the part of the air duct that protrudes from the wall according to the position and size of the strip hole in the outer frame of the valve, then install the valve frame, and then install the blade frame, that is, extend into the blade and tighten it with a screwdriver. Use screws to fix the blade frame on the connecting clip on the inner wall of the valve frame; the air outlet is directly fixed on the reserved hole, insert the valve frame into the hole, use wood screws to pass through the small holes around the valve frame, and fasten it on the reserved wooden tenon Or on the wooden frame, and then install the blade frame. When installing the air outlet without the air volume control valve, riveting or tightening the angular connection clips should be used on the frame in the air duct or in the reserved hole first, and then install the blade frame; The blades are inserted between the blades and inserted into the groove of the adjusting screw to rotate, and the connecting rod can be driven to adjust the opening of the upper blade of the outer frame to achieve the purpose of adjusting the air volume. According to the organizational situation, the blades are divided into several sections along the horizontal arrangement direction for adjustment without angle. When adjusting, special wrenches with different angles are used, and it is advisable to hold the blades and rotate until they contact the adjacent blades.
